100×2= 200
200÷3= 66.66
66.7% or 67%
Month 7 = 786.3827043 +(786.3827043*.07) = 841.4294936
Round to nearest whole number = 841 bacteria in the petri dish.
<u>Answer:</u> n=31

Answer:
A:2
B:-5
C:8
D:-147
Step-by-step explanation:
A: For this one, you can cancel out the negatives. Then just divide 14 by 7. Your final answer is 2. Final Answer : 2
B: This one you can forget about the negative for the first bit. Just divide 15 by 3 to get 5. Now the negative is only on one side of the equation so therefore we add the negative back into our answer. Final Answer : -5
C: Just divide 32 by 4 to get 8. No removal or substitution is needed for this one because both numbers are positive. Final Answer : 8
D: Multiply both numbers normally forgetting about the negative at first. 49 * 3 is 147. Now one of our numbers contain a negative so we plug back the negative into our answer. Final Answer : -147
